Abstract

The invention provides a position and communication integrated buoy used to position and communicate for underwater target. It includes: underwater acoustic transducer (8), streamlined weight (9), electric cabin (6) connecting with the underwater acoustic transducer (8) and the streamlined weight (9), buoy connecting link (3) connecting with the electric cabin (6), crowbar (7), spread-spectrum communication antenna (1) connecting with the buoy connecting link (3), GPS antenna (2), navigation mark lamp(4) and floater(5). In the invention, the system performance is reliable, easy to operate and convenient to repair. It can process information interchange with the base station of parent ship by the radio spread-spectrum communication chain to complete the emission and receiving of the underwater sound remote command, the receiving and treatment of the underwater sound request signal and answering signal, and it also has the following advantages of self-location, fault detection and convenient to reclaim.

Description

(1) Technical field [0001] The invention relates to the fields of radio communication technology, underwater acoustic communication technology and underwater target positioning technology, in particular to an underwater acoustic measurement device for positioning and communication integrated buoys. (2) Background technology [0002] At present, the underwater acoustic positioning method using geometric principles is still the mainstream of underwater target navigation and positioning technology. Among these methods, hydroacoustic positioning systems are divided into three types according to their baseline lengths: Long Base Line Positioning System (Long Base Line), Short Base Line Positioning System (Short Base Line) and Ultra Short Base Line Positioning System (Ultra Short Base Line). Base Line). Among them, compared with the short baseline and ultra-short baseline positioning system, the long baseline positioning system (LBL) has the advantages of low installation accurac...
